with yokes l1 and 21 each 22 to receive the trunmon pins holes 12 and 13 and 23 with a d nions are cut away in the center to to driving and driven the hubs being provided having through These trunterference during angular operation of the joint.

It will be observed struction shown shoulders 14 and 24 are. vided at each side of the that with the conroyokes surroun ing the base of the trunnions to provide a thrust surface.

In the construct-i on shown I provide a torque ring 30 provided with four radia'l holes 31 and two annular packing grooves 32 continuing around the periphery of the ring. The holes 31 are cut away on their sides forming the slots 33 extending to alternate sides'of the ring, two

of such slots are on one side of the ring and two on the opposite sides.

These slots are just long enough and wide enough to permit the trunnion pins slipping into place.

Recesses 36 are provided in the periphery of the torque ring 3 O which provide the inof the casing 71,

lubricant containing chambers being furnished by the wall q I The casing 71 is provided with a plurality of holes 7 3 which register with holes 37 in torque ring 30 .and holes 83 in retaining ring 81 through which bolts 84: may be passedto hold the assembly together.

Bushings are provided which are adapted tofit tightly in the seats 31 in the-torque ring 30 the annular slot 91 being provided as a means to knock the bushings out of the seats upon taking the assembly apart.

It will be observed that the bushings 90 extend beyond the ends of the trunnions but do not close the space directly under the easing thus permitting the lubricant to flow, from the lubricant containing chambers 36 to the bearings providing complete circulation of oil around the inside of the casing. Two channels 39 are provided in the torque ring to connect the lubricant chamber with the seats for the bushings.

Two annular packing rings 95 are inner side of the opening serted in the continuous annular packing slots 32 provided in the torque ring which when encased in the casing form a continuous oil sealed joint thereby preventing leakage due to centrifugal force as will be readily understood.

The casing and retaining ring are provided with oval openings to permit them to straddle the trunnions for the purpose of assembly.

The assembly of the joint is as follows: The trunnion pins 13 and 23 are driven in the holes provided in the hubs 10 and 20 and the retaining ring 81 and casing 71 are slipped over the ends of the trunnions, one over the driving trunnions and one over the driven trunnions. The trunnions are then slid into position from opposite sides of the torque ring through the slots 33 so that when the bushings .90 are driven into the seats 31 they will engage the trunnions and furnish bearings therefor. The packing rings 71 are then inserted grooves 32 and the casing 71 and retaining ring 81 are then bolted tightly together by means of bolts 84.

It will be observed that the packing rings make a completely continuous tight joint between the torque ring and the casing so that oil will be retained in the lubricant chamber.

I wish it distinctly understood that my universal joint herein described is in the in the continuous packing' that changes or variations may be made as may be convenient or desirable Without departing from the salient features of my invention and I therefore intend the folloW- ing claims to cover such modifications as nat uraily fall within the lines of invention.

I claim:

1. In a universal joint the combination with a driving and driven member and trunnions carried thereby, a torque ring provided with radial seats, entrance slots on the side thereof extending part Way through the ring and on alternate sides thereof, and two annular packing grooves in the periphery thereof, annular packing rings within the grooves, and bushings held Within the radial seats forming bearings for the trunnions.

2. In a universal joint the combination with a driving and driven member and trunnions carried thereby, a torque ring provided with radial seats and opposed slots to permit the trunnions to be inserted within the seats, bushings held Within the seats provided with annular grooves to permit removal from seats, annular packing grooves on each side of the torque ring to hold packing rings, and a casing adapted to enclose the torque ring and compress the packing to seal the joint between the torque ring and easing on both sides of the torque ring.
